基于高光谱遥感的荒漠草地围栏封育监测

Monitoring of Desert Grassland Fencing Based on Hyperspectral Remote Sensing

荒漠草地作为一个非常脆弱的生态系统,其保护对于整个生态系统的平衡具有重要意义。围栏封育对于荒漠草地生态系统具有显著的修复作用。本研究从高光谱角度,对位于乌鲁木齐市米东区的封育的蒿属荒漠草地进行监测。结果表明:利用高光谱技术可以对典型荒漠植被进行识别,将伊犁绢蒿荒漠草地的3个层片进行区分开来;通过对草地特征数据与光谱数据的聚类,发现两者对于不同封育年限及不同群落结构草地群落的识别均有较好地效果,表明高光谱数据可用于草地群落组成及结构的识别,在草地封育状况的监测方面表现出巨大的潜力。

As a very fragile ecosystem, the protection of desert grassland is important for the balance of the whole ecosystem. Enclosure has a significant effect on desert grassland ecosystem. This paper, based on the perspective of hyperspectral monitoring study, monitors the enclosed desert grassland located in Midong District, Urumqi. It is found that hyperspectral methods can be used to identify the typical desert plants, with a high classification accuracy, as well as the results of clustering of spectral data that are similar to the grass condition, it shows that hyperspectral data can be used for monitoring the grassland fencing status.
